AI Technical Summary

Benefits of technology

The system achieves an average seek time of less than 2 seconds, allowing for rapid data access and improving the competitiveness of tape-based storage against disk-based storage for larger files.

Problems solved by technology

One disadvantage of tape-based storage with respect to disk-based storage is the relatively poor access time associated with tape-based storage, with the time required to bring the tape to the tape drive and then spool the tape to the file location typically averaging about 40 seconds.

Abstract

In some embodiments, a system includes a plurality of tape reels positioned on a lower surface, a tape drive for reading data from a tape on one of the plurality of tape reels, and at least one mobile robot configured for selectively retrieving at least one of the plurality of tape reels and transporting the at least one retrieved tape reel to the tape drive.

Description

BACKGROUND[0001]The present invention relates to data storage systems, and more particularly, to mobile robots for use in tape libraries.[0002]In magnetic storage systems, data are read from, and written onto, a magnetic recording medium utilizing magnetic transducers. Data are written on the magnetic recording medium by moving a magnetic recording transducer to a position over the medium where the data are to be stored. The magnetic recording transducer then generates a magnetic field, which encodes the data into the magnetic medium. Data are read from the medium by similarly positioning the magnetic read transducer and then sensing the magnetic field of the magnetic medium. Read and write operations may be independently synchronized with the movement of the medium to ensure that the data can be read from, and written to, the desired location on the medium.[0003]In a tape drive system, magnetic tape is moved over the surface of the tape head at high speed. Usually the tape head is ...
